Description

Nonaethylene Glycol CAS NO 3386-18-3 is a high-purity, linear polyethylene glycol (PEG) derivative, specifically a nonamer of ethylene oxide. This versatile chemical intermediate is valued for its precise chain length, hydrophilic properties, and excellent solvency, making it a critical component in advanced formulations. It is essential for manufacturers in the pharmaceutical, personal care, and specialty chemical industries seeking consistent performance in synthesis and product development.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, PEGylated APIs (Active Pharmaceutical Ingredients), and as a solubilizing agent in injectable formulations.
• Polymer & Resin Modifier: Acts as a plasticizer, viscosity modifier, and cross-linking agent in polyurethane, epoxy, and other specialty polymer systems.
• Personal Care & Cosmetics: Serves as a humectant, emollient, and carrier in high-performance creams, lotions, and serfs.
• Lubricant & Functional Fluid Base: Employed in the formulation of synthetic lubricants, hydraulic fluids, and metalworking fluids due to its thermal stability and low volatility.
• Chemical Synthesis: Functions as a building block for surfactants, non-ionic emulsifiers, and dendrimers.
• Analytical & Research Chemistry: Used as a standard in chromatography and as a reagent in biochemical research.

Quality Control

Our Nonaethylene Glycol is manufactured under a strict quality management system. Each batch is analyzed to ensure it meets precise specifications for identity, purity, and composition. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, water content, and impurity profile. Our quality commitment supports applications requiring GMP-grade materials and compliance with global regulatory frameworks like REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality.
